LIVE CHAT: Yes I cheated - Armstrong admits to doping - The West Australian

He was light on the details and didn’t name names. He mused that he might not have been caught if not for his comeback in 2009.

And he was certain his “fate was sealed” when longtime friend, training partner and trusted lieutenant George Hincapie, who was along for the ride on all seven of Armstrong’s Tour de France wins, was forced to give him up to anti-doping authorities.

BELOW: ARMSTRONG LIVE CHAT

But right from the start and more than two dozen times during the first of a two-part interview with Oprah Winfrey, the disgraced former cycling champion acknowledged what he had lied about repeatedly for years, and what had been one of the worst-kept secrets for the better part of a week: He was the ringleader of an elaborate doping scheme on a US Postal Service team that swept him to the top of the podium at the Tour de France time after time.

“At the time it did not feel wrong?” Winfrey asked.

“No,” Armstrong replied. “Scary.”

“Did you feel bad about it?” she pressed him.

“No,” he said. “Even scarier.”

“Did you feel in any way that you were cheating?“

“No,” Armstrong paused. “Scariest.”

“I went and looked up the definition of cheat,” he added a moment later. “And the definition is to gain an advantage on a rival or foe. I didn’t view it that way. I viewed it as a level playing field.”

Whether his televised confession will help or hurt Armstrong’s bruised reputation and his already-tenuous defence in at least two pending lawsuits, and possibly a third, remains to be seen.

Either way, a story that seemed too good to be true - cancer survivor returns to win one of sport’s most gruelling events seven times in a row - was revealed to be just that.

Winfrey got right to the point, asking for yes-or-no answers to five questions.

Did Armstrong use banned substances? “Yes.”

Did he use EPO? “Yes.”

Did he do blood doping and transfusions? “Yes.”

Did he use testosterone, cortisone and human growth hormone? “Yes.”

Did he do it in all seven of his Tour wins? “Yes.”

Along the way, Armstrong cast aside teammates who questioned his tactics - admitting he was "a bully" - yet swore he raced clean and tried to silence anyone who said otherwise. Ruthless and rich enough to settle any score, no place seemed beyond his reach - courtrooms, the court of public opinion, even along the roads of his sport’s most prestigious race.

"I view this situation as one big lie," he said.

"The truth isn't what I said. This story was so perfect for so long.

"This story is so bad and so toxic."

That relentless pursuit was one of the things that Armstrong said he regretted most, including taking legal action against the people who were accusing him of doping, such as US Postal Team masseuse Emma O'Reilly.

“It’s a major flaw, and it’s a guy who expected to get whatever he wanted and to control every outcome. And it’s inexcusable. And when I say there are people who will hear this and never forgive me, I understand that. I do.”
